Comment 4 Stefan Cornelius 2018-06-14 05:07:54 EDT

Patch (libjpeg-turbo):
https://github.com/libjpeg-turbo/libjpeg-turbo/commit/909a8cfc7bca9b2e6707425bdb74da997e8fa499

The following section in the upstream changelog entry is noteworthy:
"[...] Because this issue only affected cjpeg and not the underlying library, and because it did not involve any out-of-bounds reads or other exploitable behaviors, it was not believed to represent a security threat."

Comment 6 Stefan Cornelius 2018-06-14 05:31:38 EDT

Statement:

This issue affects the versions of libjpeg as shipped with Red Hat Enterprise Linux 4 and 5. This issue affects the versions of libjpeg-turbe as shipped with Red Hat Enterprise Linux 6 and 7. However, the problem is limited to the "cjpeg" utility and does not affect the library itself.
